Illumination device

Abstract

An illumination device selectively disposed on an object having a first side and a second side is provided. The illumination device comprises a light-emitting module, a camera unit and a rotation mechanism. The lighting direction of the light-emitting module points towards the front of the first side. The central filming direction of the camera unit points towards the front of the first side. The light-emitting module is coupled to the rotation mechanism such that the light-emitting module is capable of rotating about an axis of the rotation mechanism. When the lighting direction falls in a first angular range relative to the axis of the rotation mechanism, the light-emitting module provides a first mode illumination. When the lighting direction falls in a second angular range relative to the axis of the rotation mechanism, the light-emitting module provides a second mode illumination. Said first angular range is different from said second angular range. When the light-emitting module provides the second mode illumination, the central filming direction falls in the second angular range.
